Is 14 a solution for the equation -5 + 2x = 23? Explain.

Answers

Answer:

Yes because after solving the equation, x does indeed equal 14.

Step-by-step explanation:

-5 + 2x = 23

2x = 23 + 5

2x = 28

x = 14

Answer:

-5 + 2x= 23 x= 14 (Correct)

Step-by-step explanation:

This is true because the first step you take to sloving this equation is to move the constant to the right. Then calculate. Divide both sides and your answer should equal x=14!

Fran solved the equation 42 = x + 23. Although her final answer was correct, she could have found it in a simpler way. Which sentence best explains why? 23 should be added to the left side and 42 added to the right side. 23 should have been subtracted from, not added to, both sides of the equation. 42 should be subtracted from both sides. The variable must be moved to the left side of the equation.

Answers

23 should have been subtracted from, not added to, both sides of the equation.

Consider the system of equations.

3x − y = 5,

2x + 3y = −15

Which value can the first equation be multiplied by to form opposite values on the y-term? A=-3 B= -2 C=2 D=3

The solution to the system of equations is .A= (-5,0) B= (5,0) C= (0,-5) D=(0,5)

Answers

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

Add (2) and (3) term by term to eliminate y

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?

Answers

Answer:

927.84

Step-by-step explanation:

The total cost of the antique clock that Janice bought is $927.82 approximately.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have:

Original price of clock = $967Sale discount = 5% on original price1% sales tax on the discounted price

Total cost = (discounted price of clock)'s price + sales tax of discounted price.

Let d = discounted price of the clock

Then, we have:

[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]

1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]

Thus, we get:

Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)

Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

Find a set of parametric equations for the rectangular equation.

Answers

9514 1404 393

Answer:

c. x = 7-t; y = -1/(t -7)

Step-by-step explanation:

To find the parametric equation for x, use the equation for t and solve for x.

t = 7-x

x = 7 -t . . . . . . add x-t to both sides

To find the parametric equation for y, substitute the equation for x.

y = 1/x

y = 1/(7-t)

To make this match the available choices, we need to multiply numerator and denominator by -1.

y = -1/(t -7)

The parametric equations are ...

x = 7 -t; y = -1/(t -7) . . . . . . matches choice C

Answer:

The triangle is an obtuse isosceles triangle

Step-by-step explanation:

This is an obtuse isosceles triangle because it has two congruent sides, making it an isosceles triangle, and there is an obtuse angle, which is any angle greater than 90°.

The interior angles of a triangle add up to 180, so let's make an equation.

132+2x=180

Then solve for x

subtract 132 from both sides

2x=48

Divide by 2 on both sides

x=24

The answer would be X=24 obtuse isosceles triangle

13. Connie wants to paint one wall in her living room. Along the wall, she
counted 60 pieces of hardwood that are each 6 cm wide. The wall is 8 feet
tall. Estimate the area of the wall she plans to paint. Round to the nearest
square foot. (1 foot approximately 30 cm)

Answers

Answer: Approximately 96 square feet

======================================================

Work Shown:

1 ft = 30 cm

1 ft = (5*6) cm

1 ft = 5*(6 cm)

1 ft = 5*(1 board width)

1 ft = 5 board widths

12*(1 ft) = 12*(5 board widths)

12 ft = 60 board widths

12 ft = 1 full wall length

The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.
